Vlan (Vlan Configuration) - Cisco Catalyst 3550 Command Reference Manual

Chapter 2 Cisco IOS Commands

vlan (VLAN configuration)

Use the vlan VLAN configuration command to configure VLAN characteristics for a normal-range
VLAN (VLAN IDs 1 to 1005) in the VLAN database. You access VLAN configuration mode by entering
the
parameters to delete a VLAN. Use the no form with parameters to change its configured characteristics.
Extended-range VLANs (with VLAN IDs from 1006 to 4094) cannot be added or modified by using
these commands. To add extended-range VLANs, use the
enter config-vlan mode.
Note The switch supports only Ethernet ports. You configure only FDDI and Token Ring media-specific
characteristics for VLAN Trunking Protocol (VTP) global advertisements to other switches. These
VLANs are locally suspended.

ID of the configured VLAN. Valid IDs are from 1 to 1005 and must be
unique within the administrative domain. Do not enter leading zeros.
(Optional) Specify the maximum number of all-routes explorer (ARE)
hops for this VLAN. This keyword applies only to TrCRF VLANs.
Valid values are from 0 to 13. If no value is entered, 0 is assumed to be
the maximum.

(Optional) Specify the logical distributed source-routing bridge, the
bridge that interconnects all logical rings having this VLAN as a parent
VLAN in FDDI-NET, Token Ring-NET, and TrBRF VLANs.
Valid bridge numbers are from 0 to 15.
The type keyword applies only to TrCRF VLANs and is one of these:
